Size: Adults may range from 7-17 inches (18-43.2 cm) in females
and 5-9 inches (12.5-23.5 cm) in males.
Description: A large, flattened, aquatic turtle whose carapace
and plastron are covered by rubbery skin. Softshells have a sandpaper-like texture
to their leathery shell. Olive-gray to yellowish brown coloring with patterns
of spotting are found along the carapace. They also have a long neck and a tubular
nose that they breathe through like a snorkel.
Range and Habitat: Eastern Spiny Softshells (Apalone spinifera
spinifera) are found in the extreme western mountains of North Carolina.
Gulf Coast Spiny Softshells (Apalone spinifera aspera) are found in southern
regions of North Carolina, ranging north along the major river systems. Although
they may be found in all fresh bodies of water where sand and mudbars are present,
softshells prefers large streams and rivers.
Behavior: These turtles are strong swimmers in the water and fast
movers on land. Softshells often bask on sandbars and will often lie buried
in sand in shallow water, using their long necks are used to protrude to the
surface of the water to obtain air. Although they will sometimes leave the water
to bask they are generally very wary and often rush to the water at the first
sign of an intruder. Softshells feed primarily on fish, crayfish, and aquatic
invertebrates.
Reproduction: Spiny Softshells generally lay 12 - 18 spherical brittle-shelled
eggs in the early summer. It is thought that females may lay multiple clutches
per season. Nests are generally located close to water, often on sand or gravel
bars. Young emerge about 80 days later and are usually 3 - 4 cm across.
Status:
Eastern Spiny Softshells are listed as a special concern species under North
Carolina law.
